FLYING-MACHINE.

To all whom it may concern:

Be it known that I, FRANK VOGELZANG, a citizen of the United States, residing at Rock Valley, in the county of Sioux and State of Iowa, have invented new and useful Improvements in F lying-Machines, ofwhich the following is' a specification.

y invention relates to a new and useful improvement in flying machines and has for its primary object to so construct a flying machine as to provide for the adjustment of the propellers in such manner as to permit the lifting of the machine substantially vertically from the ground and then by re-.

adjusting the propellers give said machine a forward movement. I

A further object of. my invention is to provide for the attachment'of the wings or planes to theflying' machine in such manner that they maybe adjusted in unison at various'angles to the body of the machine.

A still further object of my invention is to provide simple and effective mechanism for bringing about the various adjustments and operations of the machine, the action of said mechanisms being under the easy control of the operator.

With these ends in view, this invention consists in the detailsof construction and combination of elements hereinafter set forth andthen specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this apphcation, in which Figure 1, is a plan view of my improved flying machine.

portions being 'sectioned away to more clearly show the operating mechanism.

one of the'trap doors.

In carrying out my invention as here embodied, 1 represents the'body of the machine carrying the hood or aviators inclosure 2 and upon the forward portion of the body is located the engines 3 here shown as two in number, and the power shaft of each of these engines has secured thereon a bevel gear '1, and each of these bevel gears meshes with a corresponding bevel gear 5 secured upon the outer end of a short shaft 6, said short shafts carrying the female clutch mem bers 7 into which fit the male members 8 of said clutches. The clutch members 8 are secured upon the outer ends of the coupling shaft 9 journaled in suitable bearings 10 and The power shafts ofthe engines also have secured thereon the bevel gears 13 or these gears may be formed with the bevel gears 4, each of the bevel gears 13 meshing with a bevel gear 14 which latter is secured upon the counters'haft 15. Y

16 represent two gear boxes each of'which is journale d on the trunnions 17 fitted in the bearings 18 supported upon the frame of the machine, and one of the countershafts 15 passes through each of the gear boxes and has secured thereon the bevel gear 19 and loosely mounted thereon the bevel gear 20 both of which said gears mesh with a bevel- 7 gear ,21 secured on the inner end of the propeller shaft 22.

The propeller shaft 22 is journaled in the casing 2-3 which latter is braced by therods 24 and cross bar 25, and the outer end of the casing 23 is fitted to slide in the segment 26 the studs 27 projecting from the casing into the slots 28 formed in the segment so as to properly guide this outer end of the casing.

29 represent the propellers, one of which is secured to the outer end of each of the 'shafts 22.

The segment 26 being secured at each-end to the frame of the machine so that the center of the circle of which it forms a part coincides withflthe center of the trunnions 17, the propeller shaftcasing may be swung from a horizontal position to a vertical position as clearly shown. While this may be effected in any convenient manner the mechanism I have here shown for accomplishing this result consists of a segmental gear 30 formed around a portion of each of the gear boxes 16 and having the pinions 31 meshing therewith, said pinions being secured upon the outer ends of the operating shaft 32- which latter carries the hand wheel 33 in easy reach of the aviator. By the operation of this hand wheel the propellers may be swung to any position from a horizontal to a vertical or stopped at any intervening point without interfering with the rotation of the propellers by the enginesas. will be readily understood. I

34 represent the wings which may be of any desired construction of either the single plane or double plane type, said wings being hinged to the frame of the machine as indicated at 35 so that they may be swung from a horizontal position downward to a considerable angle, and if found desirable may be arranged to be swung upward at an angle above the horizontal. In order that these wings may be readily controlled by the aviator and set at any desired angle in unison, I provide an operating screw rod 36 in which runs the nut 37 the latter being guided in the frame 38, and to this nut is pivoted the rod 39, at 40 their upper ends being pivoted at 41 to the underside of the wings, while upon the upper end of the screw rod 36 .is secured a hand wheel 42 in easy reach of the aviator. From this 'it will be seen that when the wheel 42 is properly manipulated the nut 37 will be raised or lowered and consequently the wings will also be raised or lowered in unison.

In order that the propeller shafts "may be brought'to a true vertical position, I rovide cutaway portions 43 in the top' 44 o the aviator inclosure and arrange the trap doors 35 so that they will slide back and forth to close theseopenings, and in order that these' trap doors may automatically close when the propeller shafts are swung out of the openings coil springs 45 are attachcd, to said doors in such manner as to normally hold them in their closed-positions yet permitting them to-be forced backward by the propeller shafts from the latter coming in contact therewith.

In the rear portion of the body of the machine i'sjou'rnaled a short shaft 46 upon the outer ends of which are secured the vanes or rudder planes 47 for directing the up and down course of the machine, and these planes are connected by therod 48 to an operating lever 49 in easy reach of the aviator, and 50 represents the usual plane or rudder for steering the machine sidewise and may be connected in the usual manner to a love in easy reach of the aviator.

Y beginning of a flight to raise the machine From the foregoing'description the operation of my improved flying machine will be obviously as follows Where it is necessary or; desirable at the directly upward the propeller shafts are adjusted to a vertical position so that when the engines are put in operation the revolving of these propellers will lift the machine substantially in a vertical line and after the desired height has been reached the propeller shafts are gradually swung downward until reaching a position for giving the machine the proper forward motion. As the propeller shafts may be set at various angles relative to the machine a more or less upward pull upon the machine may be had during its flight forward thus causing the propellers to assist the wings in lifting the load, and this is of great importance where the machine strikes what is known as air pockets which would have a tendency to cause the machine to take a head on dive since the propellers may be swung upward to a degree sufiicient to lift the nose of the machine thereby preventing serious accidents which often occur from this cause. Another advantage in having the propellers adjustable to diflerent positions is that when alighting far better control may be had by the aviator since the forward wheels of the machine may be brought in contact with the ground with less violence and when necessary lifted over serious obstructions.

When the machine is lifted vertically as 100 before. described the vanes or planes 47 may be swung downward until they reach a vertical position, thus relieving the wind pressure upon the rear of the machine caused by its upward movement or these planes may be 105 'set at such an an 1e as will balance the superior weight of t e engines. a

The adjustability of the wings provides for various conditlons met in the flight of the machine and especially in descending as by setting the wings atra considerable angle to the body of the machine the general effect of a arachute is obtained.

0 course I donot wish to be limited to the exact details of construction as-herein shown as these maybe varied within the limits of the appended claims without departing from the spirit of m invention.
